All items are delivered in-game via an account-wide mail. Items can only be accepted by one Knight on the account. Items that bind will bind to the Knight that accepts the items.

Armors and Helms are costume items. Armors, Helms, and Sparks of Life are bound upon acceptance.

Please note that players who access the game through Steam will not see the Guardians Armor Pack in the ingame Energy Depot, but instead can buy it as DLC from the Steam Store: http://store.steampowered.com/app/206522/

The Guardians Armor Pack was introduced in the 2012-07-13 promo event.
